To all whom t may concern:

Be it known that I, LoUrs `GrArrrAN Acos- TINI, a citizen of theRepublic `of France, residing at 1 Rue Davy',Paris, France, haveinvented certain new and r`useful Improvements in Hair Curlers, of whichthefollowing is a specification. .s 1 y f This invention relates to'improvements in hair curlers of the typeused for Vper-I'nanentlyfwaving ladies hair.

Haircurlers `of this tyipe usually consist of a slotted end piece an aytube connected ytogether by'a spring controlled ratchet de- `viceenclosed within the latter. kers are usedA in the following manner.

These curls A lock of hair is taken andtiedtoget'her near the scalpwithapiece of string. The string ,in "an, electric is 'iixed'in the slotoflthe end piece and the `hair Ais wound on the tube, thev end of thelhairbeing fastened with another piece of string. `The end pieceyisfthen held with pliers and thetube is turned so as to tighten thelcoils on the curler; Iafter which the hair is moistened with asolutionv of bo'rax and enclosed in a apercapsulewhich isplaced al)heater.`

The prineipai disadvantages Ofsuh curi- Lers are, first, that' the hairvmay be damaged because 'of the necessity of holding the end piece withvpliers when tightening the coils upon the curler; second, 4that it isdifficult to remove ythe curler withoutdamaging the 'hair;` and third,that it isimpossible to clean the enclosed parts ofthe curler,\whichparts are very 'liablefto corrosion because of the use ofbora'x. A A

According ytoy this invention `I employ a. curler in which the end pieceis secured to a central rod passing right through the tube and fittedwith `a milled Aknob which is pressed by a spring against the other endof the tube so as to prevent rotation, either by the friction betweenthe two parts, or preferably by the definite engagement of teethprovided on the two parts. In this way the coils of hair may betightened after they have been wound upon the curler by merelycatchinghold of the milled knob, pulling it out of engagement with thetube, and turning the one relatively to the other. After treatment thehair. can be loosened by pulling out the milled knob and turning in theop osite direction, but I prefer to facilitate tllie undoing of the hairby slightly tapering the whole curler, and by employing a vertical slotin the end piece instead of the vusual hook,'which is liable to catch inthe hair. I prefer also to screw the end: piece to the central rod, andto extend the latteratjthe other `end so that it passes right 'throughand projects beyond the milled knob. The former enables thedevice to betaken to pieces for cleaning, and the latter enables the endpiece andthe tube to be slightlyseparated `for thepurpose of yoilreferencefigures denote the same lparts Figure `l is a view of the completecurler, Figure curler, j

`Figure 3 is an end view of Figure 2,

Figure 4 is a view of the centralrod and milled knob, i

Figure 5 is a view in section, j

Figure `6 is'a section of Figure 4, Figure 7 is a view of the'centralrod, Fig. 8 is a view showing th'ecurler inuse. Inthese figures 1 is thetube provided with teeth 2 at one end which fits into the annulargroove?, inthe milled knob 4. 5 is the central rodhaving" at one end theVthread screwin'g into the liole? in the `end piece 8, which is providedwith a longitudinal slot 9. At the other end of the central rod 5 arelprovided a hole, 10, a longipassesv throughthe hole 10, and the otherend presses against the 'inside of the bent `over edge of thecylindrical extension 15 of the milled `knob 4. The pin" 14 passesthrough 'the slotv 13 andits tightly into the milled knob 4, so that thelatter can slide but cannot turn upon the rodl 5. The extension 12 ot'the rod 5 passes through a hole in, and projects beyond. the milled knob4.

It will be seen that the spring 11 causes the tube 1 to be grippedbetween the end piece 8 and the milled knob 4, and that the pin 14 ofthe latter is thus pressed into the teeth 2 of the former so that thetwo are locked together and have to be pulled out ot' engagement inorder to be turned. The relative turning of the milled knob 4 and thetube 1 after they have been pulled out of engagement causes the relativeturning of the end piece 8 and the tube 1, and .thus permits of thetightening or loosening of the ofthe end piece'partly i is a section ofthe tube ot'jthe the rod 5 the latter may be taken out 'of the' tube land cleaned, while by pressing the projection 12 the end piece 8 will bepushed ,away from the tube l so that the "end of the ,rod 5 may be oiledwithout being disI man'tled.

Having now particularly described and Aascertained the nature of my saidinvention :and in what manner the same is to be pertormed l declare thatwhat l claim is l. lA hair curler, comprising a tube, a cen-y tral rodinserted through the bore 'of the tube and projecting therebeyond atopposite ends; an vend piece on one end of the rod; a knob on the otherend ot said rod.; and a spring acting to normally grip the knob to theadjacent tube end and thereby prevent relative rotation between therod'and 2. A hair curler, comprising a tube having a toothed end; acentralv rod inserted. through the bore ot the tube and Aprojectingthere-y beyond at opposite ends; a knob onl the y"end of the rodadjacent thevtoothedjend of the tube and having teeth for engagementwith the tube teeth to ,prevent relative. rotation between the tube androd; a spring within saidr knob acting to normally maintain the two setsoli'teeth engaged; land an end piece on thefotherend ofthe rod.

3. ,hair curler, comprising ya tube;- a central rod inserted through theborey of the tube and projecting therebeyond atoppos-ite ends; a knobmounted to slide fon lone end-of the rod but held against rotationonsaidend; a spring within the knob acting to normally couple the latter andthe adjacent tube 'end to .prevent relative rotation between the rod andtube until such coupling is terminated by thevsli'ding movement ot' theknob on fsaid rod; and an end piece-on the 'other end of the rod.

4. vA hair leurler,v comprising a tube; :a

between the rod and tube until such coupling is terminated .by thesliding movement of the knob; and an end piece-on the other end of therod. i y

5. A hair curler, comprising a ltapered tube, a central rod insertedthrough the bore of the tube -andprojectingy beyond the same atlopposite ends; a knob mounted on the end of thefrod adjacent the largerend of the tube'land adapted to slide on said rod, end but held againstrotation thereon; a spring normally fcoupling said knob to said tubeen'd to` prevent. relative rotation between the rod and tube` until suchcoupling is terminated by the sliding movement of the knob; and aremovable end piece on the other end of the rod.

6. A hair eurler, comprising atube; a central .rod Ainserted throughthebore of the tube and projecting therebeyond at opposite ends; a knob yonone end of the rod; means associated with the knob for .normal-lypreventing yrelative .rotation between the rod and tube .fand an endpiece on the other end ot theirod. y y 7. A hair eurler, comprising fatapered tub'e; 'a central rod inserted through Vthe bore of the tube`and projecting therebeyond at opposite ends; -a knob lon one end of therod; means associated with the knob for normally preventing relativerotation between the rod and tube; and an end .piece removably threadedon the other end of the rod.

In testimony whereof I aflixed my signature.
